I just bought a house with an inground pool and just replaced the vinyl liner and got it set up with water from a company and hose water. My alkalinity & Ph are good but I cannot get the chlorine to show up. I have a Hayward Chlorinator and have two 3in tablets- in it. I have shocked it with power powder (diluted it in a bucket of water first). The only time I had a reading of chlorine was about 1/2 hour after adding the power powder. I did buy some liquid chlorine bleach at the store (after reading pool solutions) that I was going to add at night into the pool skimmer but wasn't sure if I could do that with the tabs in the chlorinator. My guess is that I have maybe a small about of stabilized chlorine from the tabs but no unstabilized chlorine? I just ordered a Taylor test kit and it should arrive any day now. Still would like to get some chlorine registering before then.
